LAMP-EXTINGUISHER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES E. ABBOTT, of Maldcn,'in the county oiMiddlesex, and State of Massachusetts, have invented a new and usefulImprovement in Lamp-Extinguishers; and I do hereby declare the followingto be a full and correct description of the same, reference being bad tothe accompanying drawings, in

which--- Figure 1 is a. perspective view of a. lamp-top having myimproved extinguisherapplied, it being shown in the position it occupieswhen the lamp is extinguished.

Figure 2 is a detail view of the lever which operates the extinguisher;and

Figure 3 is apcrspective view, showing the relative positions of theparts when the lamp-tube is open, as when the lamp is'burning. I i 1 Thesamelctter marks the same part whenever it occurs.

This invention is an improvement on the lamp-extinguishers invented byme, and patentedJuly 3, 1866,

I and November 13, 1866. In the first ofthese, the supplementalwick-tube, carrying the extinguishing-lid, was

operated by a rack and pinion. In the second, I substituted a lever forthe rack and pinion as the means of operating the tube; but in both, theforce of gravity was alone relied upon to cause the fall of the liduponI the top of the'tubc to extinguish the lamp.

The present invention consists chiefly in the addition of a positivemovementt o the force of gravity, to insure the fall of the lid and holdit closed. I 7 I It further consists in the use of a spring, to producefriction upon the lever suflicic'nt to hold it in any position; and theemployment of a stop to limit the upward movement of the lever; all ashereinafter set forth. To enable others to make use of my improvement, Iwill proceed to describe its construction and operation, referring tothe drawings, whcreon A marks the ordinary 1amp-top, the cap beingremoved to show more clearly the wick-tube, and the parts connectedtherewith. b'is the wick-tubc, o n the outside of which slides up anddown the tube a, to which is hinged the cover or lid 11, the hinges'ebeing so arranged that the lid will fall by gravity when the tube 0 isin its uppermost position, as in fig. 1. From the rear side oflid clprojects a tongue,

t. g h is a lever, which works on pin 2' as its fulcrum. A spiralspring, 8, surrounds this pin, and bears against the lever h, to hold itin any position required. The lever it has a finger-piece at its outerend, by which it is conveniently operated. Its inner end is flattened,and has a slot, k, in it, which receives and moves on a pin, Z,

projecting from the side of tube a, so that the operation of the leverwill raise or lower the tube c, as may be desired; the throw of thelever-being suflicient to'earry the tube'so high that the lid, whenclosed, will be above the top of the wick. From the extreme inner end oflever 7t projects a. bent finger, m, arranged to come into contact withthe under surface of tongue t on the rear of the lid 02 when the tube 0is approaching its highgst position. It closes the lid d, and holds itclosed, while the tube 0 remains in its highest position. A notch, n, inlever 71, operates as a stop, by engaging with the side of-thc1an1p-top, to prevent the inner end of lever It from rising too high, soas tobend the tongue 12, or force the lid 01 from its hinges.

The operation is the .same as in my previously-patented extinguishers.When the lamp is burning,'or about to be lighted, the parts have therelative positions shown in fig. 3. To extinguish the lamp, it is onlynecessary to depress the outer end of lever 71, when the parts will bebrought into the positions shown inj fig. 1, the lid d being closed overthe wick.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- 1. The arrangement, for conjointoperation, of the tongue t and finger m, as and for the purpose setforth.

2, The spring 8, in combination with the pin 2' and lever h,arranged'and operating asspecified.

3. The stop-notch n'on lever It, operating as and for the purposedescribed.

The above specificationoi' my said invention signed and witnessed atBoston, this 27th day of July,
